Systems and methods for registering machine type communications devices and scheduling machine type communications device transmissions

A method of scheduling registered Machine Type Communications (MTC) device transmissions by a network element, the method comprising:

• detecting, by the network element, that a trigger event has occurred based on a trigger mechanism;
• and
• receiving, by the network element, a MTC device transmission from a MTC device associated with the trigger event over a resource block based on the detecting, the resource block being previously assigned to the MTC device such that the network element is not required to perform a signaling procedure with the MTC device in order to transmit the MTC device transmission,
• receiving a message including a determined timing advance based on a delay time, the delay time being based on a measured round trip propagation delay between the MTC device and the network element if the trigger mechanism is one of a paging trigger and an event trigger, and the delay time being based on a measured one way propagation delay between the MTC device and the network element if the trigger mechanism is a timer trigger;
• and
• adjusting a start time of the MTC device according to the timing advance.

A method of transmitting a Machine Type Communications (MTC) device transmission by a MTC device that is registered with a network element, the network element scheduling MTC device transmissions, the method comprising:

• receiving, by the MTC device, a message indicating that the MTC device is registered with a network element, and at least one resource block assigned to the MTC device to transmit on;
• transmitting, by the MTC device, the at least one MTC device transmission over the assigned at least one resource block when a trigger event occurs, the at least one resource block being previously assigned to the MTC device by the network element,
• receiving a message including a determined timing advance based on a delay time the delay time being based on a measured round trip propagation delay between the MTC device and the network element if the trigger mechanism is one of a paging trigger and an event trigger, and
• the delay time being based on a measured one way propagation delay between the MTC device and the network element if the trigger mechanism is a timer trigger;
• and
• adjusting a start time of the MTC device according to the timing advance.
